Why IQOS Uses Temperature Control — Full Scientific Explanation (2025)
Temperature is the defining difference between IQOS and cigarettes.
By heating tobacco at precise levels, IQOS prevents combustion and generates a reduced‑exposure aerosol.

IQOS Heating Technology Overview
📌 The entire design of IQOS revolves around the idea: no fire = less harm from tobacco.
Combustion Creates Most Harmful Compounds
Cigarettes burn at 700–900°C.
At these temperatures, thousands of new chemicals form from fire reactions:
• polycyclic aromatic hydrocarbons
• carbon monoxide
• combustion particulates
• carcinogenic tar components
How tar is formed during burning
📌 Remove fire and you remove the chemical reactions that create most cigarette smoke toxicants.
IQOS Limits Heat to Prevent Burning
IQOS controls temperature at about 300°C to:
✔️ avoid ignition
✔️ avoid smoke
✔️ eliminate ash
✔️ reduce exposure to harmful substances
📌 This temperature is high enough for nicotine aerosol — but too low for combustion.
More Stable Nicotine Delivery for Adult Smokers
Controlled heating ensures:
• consistent nicotine extraction
• smooth sensory experience
• predictable satisfaction from every stick
Nicotine absorption explanation
📌 Stability helps adult smokers switch away from cigarettes successfully.
Temperature Sensors Protect Against Overheating
IQOS continuously monitors:
• heat profile evolution
• user draw pressure
• session timing
• airflow resistance
If overheating risk appears:
▶️ IQOS shuts off automatically
📌 Technology makes heating safe without requiring user judgment.
Different Models Use Different Heating Systems
Model Heating type Why temperature control matters
IQOS 3 DUO and earlier Heating blade Must maintain contact with tobacco
IQOS ILUMA series Induction Smartcore Controls magnetic field heating
📌 Both rely on thermal precision — just applied differently.
Temperature Control Prevents Harsh Sensations
Burning materials cause irritation:
❌ hot smoke
❌ harsh particulate impact
❌ throat dryness from combustion residues
IQOS avoids burning → more comfortable sensation
HEETS strength levels explained
📌 Sensory comfort improves switching outcomes for adult smokers.
Temperature Precision Maintains Tobacco’s Aroma Profile
Real tobacco flavors degrade at high heat.
Precise heating preserves:
• characteristic aroma compounds
• familiar tobacco taste
• smoother inhalation
📌 Better taste = fewer reasons to return to cigarettes.
Why Temperature Is Core to Harm‑Reduction Science
Without precise control, burning could occur →
exposure would increase → harm‑reduction purpose would be lost.
Temperature and Nicotine Delivery — Why Stability Matters
For adult smokers transitioning from cigarettes, nicotine delivery stability determines success.
If aerosol feels too weak or inconsistent:
• cravings may return quickly
• switching confidence decreases
• relapse to cigarettes becomes more likely
IQOS uses active temperature regulation to ensure:
✔️ consistent aerosol density
✔️ familiar nicotine onset
✔️ satisfying throat impact without smoke harshness
Nicotine delivery speed comparison
📌 Reliable delivery supports complete cigarette replacement — the core goal for adult smokers.
Preventing Pyrolysis and Limiting Harmful Reactions
Temperatures above ~400°C expand pyrolytic reactions that create harmful chemicals.
IQOS keeps the temperature below the threshold where:
❌ tobacco carbonizes
❌ solid particles form
❌ smoke chemicals appear
📌 Temperature control is not optional technology — it is the safety principle behind heating tobacco.
